Product advantages

Emission standards: Euro V and Euro VI, with advanced Woodward electronic control system adopted.
Power performance: Improved output torque at low speed and maximum torque and good responsiveness during acceleration and start-up meet the power requirement of the vehicle.
Economy: The fuel economic zone shifts to the low speed range; squish effect is strengthened and combustion speed is increased; the intelligent ignition coil increases ignition energy, reduces load cycle variation of low-speed part, and reduces fuel consumption.
Comfort: Low vibration and low noise,Noise is reduced to 79dB(A) @ idling, 93dB(A) @ rated power.
